1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Inflammatory myofibroblastic tumor (IMT) of the uterus is a rare low-grade malignant mesenchymal tumor characterized by its potential for recurrence and metastasis. The compact fibrous subtype can be easily misdiagnosed as a leiomyoma when it lacks a prominent inflammatory cell infiltrate. To enhance understanding of this disease and improve diagnostic vigilance, we present two cases of IMT exhibiting morphological features similar to leiomyomas for analysis. The ages of the two patients were 26 and 34 years, respectively. In Case 1, microscopic examination revealed densely packed spindle-shaped cells arranged in intersecting fascicles, with scattered inflammatory cells in the background and without myxoid stroma. The morphology closely resembled that of a leiomyoma, with only focal invasive growth. Case 2 involved a pregnant woman with a tumor that exhibited well-defined boundaries, varied cellularity, and compact regions with spindle cells arranged in bundles, along with stromal lymphocyte infiltration, while the loose areas demonstrated myxoid matrix. Immunohistochemical analysis indicated that both tumors were diffusely positive for ALK and expressed several myogenic markers. Fluorescence
